Check out this first train (imaginary) to Uttarakhand (Rishikesh) from Tripura's capital city, Agartala via Assam, West Bengal, UP, etc. Interesting fact about this train is that it could be the only train to Uttarakhand from AGTL to RPH and only direct train to Rishikesh from AGTL to SPN as well as only super fast train in the entire route.
